We rented a car last weekend, as we frequently do. Upon returning the car they presented me with the gasoline bill as usual. Only this time, bill reads about 40% more than it should, according to the onboard computer's calculated average consumption for the trip. I tell the (young) guy behind the counter that there is an error with the bill, and I'm not going to pay it. Obviously, the tank was not full when I received the car. He wants to know why. I explain. Hilarity ensues.
Him: "Well, you know, the average consumption is just that, average. It's too slow to register peak consumption."
Him: "Well, you know, the average..."
Me: "Yes I heard you the first time, I'm just not sure what you're talking about. Average is average, both peak and extreme low consumption gets recorded, and average is based on that."
Him (patiently): "No, no, look here. If you drive a stretch with a really, really low consumption, you can then go to a race track and empty the tank there, and the average reading will never change. I can guarantee you the tank was full when you received the car." Looks gleamingly over to the young female co-worker standing next to him.
Me: "You guys rent Toyota Yaris for track use? You're saying the on board comp doesn't react to a 40 percent increase in the AVERAGE figure? Seriously, how exactly are you planning to "guarantee" anything when the facts don't support you? Regarding your math, definition of average... etc. etc. etc."
Him: (very irritated): "Did you understand any part of what I just told you?"
Me: "No, because you make no sense and bring shame upon the math teacher whose classes you frequently skipped, you ignorant punk." OK, not those words, but I'm getting really fed up.
We take one more round, me explaining the facts, him "explaining" his wonderful consumption theories and getting more and more upset as it sinks in he is an ass, and everyone including his co-worker knows it. But there's no way he can back up now, not with the audience. I ask to speak to his boss, he tries calling him, no luck. Turns out the boss is his dad, the owner of the gas station.
I offer to pay what I consider a reasonable part of the gas bill, based on the average reading. That's a NO! I'm running out of time, this is a small amount of money. I take his daddy's contact info (he is very reluctant to give that either), pay the bill and inform him I will be back to receive his personal apology once we get things straightened out with his father. At this point, the female co-worker exits the stage with some excuse. He is one very red kid.
Today, his father calls me and apologises profusely. Their mistake, the tank wasn't full when I got the car. The whole bill will be refunded. I'm considering going back to see if the kid has what it takes to admit the mistake and apologise.
I seldom wish I owned a car, but that evening was definitely one of those days. [/rant]
